Bitstream File Not Found/permissions

[FlippedBit]

Hello everyone!

 

I'm new to these forums, so please let me know if I'm posting this question in the wrong place.  

 

I just received my Basys3 board in the mail today.  Since I'm fairly new to FPGAs, I decided to start off by simply programming the device with the Abacus Demo.  While I've been able to program the device with the demo, I can only do so when I move the bitstream file out of my project directory.  The project is located at C:/Users/Chris/Desktop/GraduateProject/Basys_3_Intro.  When I attempt to program the Basys3 with the bitstream file that is located within a subdirectory of the project, I get the following error: 

 

ERROR: [Labtools 27-2149] File C:/Users/Chris/Desktop/GraduateProject/Basys_3_Intro/Basys_3_Intro.runs/impl_1/Basys3_Abacus_Top.bit not found. Check file name and file permissions.

 

However, if I copy the bitstream file to my desktop, so that it's located at C:/Users/Chris/Desktop/Basys3_Abacus_Top.bit, then the file can be accessed and the Basys3 is programmed without any errors.  Any idea what's happening here or what I'm doing wrong?  Thanks!

Ah, the dilemmas with file names :-)

I'm not sure exactly how the error gets caused, but it could be as simple as having a file name that is too long to be directed to. 

Keeping file names shorter than 260 characters is often a safe bet. 

There are issues with other applications (TI's Code Composer Studio or Atmel's AVR STudio). 

I'm glad you got it working though!
